Bettcher is one of several candidates the Cardinals have interviewed. After spending eight years as a college coach, Bettcher spent one year as outside linebackers coach with the Colts in 2012, when Arians was the team’s interim head coach for most of the season, then went with Arians to Arizona and spent two years as the Cardinals’ outside linebackers coach and three years as defensive coordinator.

“He’s ready to be a head coach anywhere,” Arians said.

The Cardinals have indicated that they will take their time with their search. Several of their candidates are assistant coaches on teams that are still in the playoffs.
